So maybe this was a bit reckless, but I went ahead and licked some of the runes. I'm sorry! I was very careful to lick as gently as possible.
And while this has contributed little to linguistic comprehension (and perhaps much to extra wooziness -- hard to tell), I'm now pretty sure I'm seeing things I couldn't see before:
A hole NE of here? A doghouse under construction to the west? A ghostly and faintly flickering research lab due south of here, and an even more ghostly (and even more faintly flickering ) waterlogged home directly on top of (and inside of?) our nice tunnel home? Yikes!
I think I'd better lie down for the rest of the day, but I'm taking a notebook with me, and I'll yell out if I have any etymological insights.
